DUMP-CAR.

Specification of Letters Patent.

Application filed August 15, 1911.

To all whom it may concern Be it known that I, HARRY E. THOMPSON,

: Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Dump-Cars, of which the following 1s a specificatlon, reference be- I inghad to the accompanying drawing.

My improvement relates particularly to dump cars constructed for the tilting of the car body to either side and comprising mechanism for controlling such movement of the car body byvmeans of air or steam power applied through cylinders and plstons.

The objectof the improvement is to provide a powerful and efficient and easily-controlled mechanism for tilting and righting the bodies of large dump cars used in construction work and for similar purposes.

The present improvement is especially applicable to the car which is made the subject matter of Letters Patent of the United States No. 953,865 granted to Robert L. Sites, April 5, 1910, my improvement being designed to constitute a strong support for the two lifting cylinders of said patent. In constructing my improvement strong metal should be used. i

In the accompanying drawings, Figure 1 is a transverse sectional view of a portion of a car embodying my improvement, said section being on the line, 1l, of Fig. 2; Fig. 2 is a section on the line, 2-2, of Fig. 1; Fig. 2 is a detail view illustrating the manner of securing the cylinder to the draft sills. Fig. 3 is a section on the line, 33,

of Fig. 1; Fig. 4 is an elevation, looking toward the right in Fig. 1; Fig. 5 is a sec tion on the line, 55, of Fig. 1 the cylinders being omitted.

Referring to said drawings, B, B, are two horizontal, parallel, channel beams or draft sills which constitute the chief members of the under-framing of the car. Said sills are movably to the bottom of the car body, D,

Only one such chair is shown in the draw ings; but any desired number of such chairs and hinge members may be used to give the may be used to retain'said body in the horizontal position.

The two cylinders, A, A, are to be sup ported at opposite sides of the pair of draft sills, B, B, and the structure for supporting said cylinders is applied to said sills, as will be next described.

To the inner face of each draft sill is ,applied a wall plate, 1, said plates being horizontally opposite each other and each having its upper edge even with the upper edge of the adjacent sill and extending downward some distance below said sill. Along each upright edge of each wall plate, 1, is placed an angle plate, 2, as long as the height of the draft sills, one flange of said angle plate being approximately even with the adjacent edge of the adjacent wall plate, 1, and the ot-herfiange of said angle plate being directed toward the corresponding flange of the angle plate which is applied'to the adjacent edge of the opposite plate, 1. Bolt-s or rivets, 3, extend through the angle plates, 2, the plate, 1, and the draft sill, B, and bind said parts rigidly to each other. Two upright channel plates, 4:,

are placed upright and transversely between the plates, 1, 1, each such channel plate being of proper width to make its outer flange faces fit against the adjacent facesof the plates, 1, and said channel plates extending bolts or rivets extend only through said flange and said plate.v Bymeans of such bolts and rivets, said parts are rigidly secured to each other. 7

Below the draft sills, a gusset plate, 7, is applied to the flat outer face of each 50 of said beams.

7, and the channel plate, 4c, so far as these three parts over-lap each other; and bolts, 10, extend through said beam and said gusset plate so far as said parts over-lap each other; and above the beam, bolts, 11, extend through the gusset plates and the channel plate, 4.

From the foregoing it will be observed that the cross-beams are separated from each other a distance equal to the distance from the outer face of one gusset plate to the outer face of the other gusset plate; and it will be observed that each end of each cross-beam extends outward beyond the adjacent edge of the gusset plate.

Between the cylinders, A, a binder plate,

12, is placed across the two sills and secured thereto by bolts or rivets, 13, extending through the edges of said plate and the upper flanges of the sill. And from each gusset plate, 7, a plate, 1 1, extends across the lower edges of the sills and is secured to said sills by means of bolts or rivets, 15, extending through the edges of said plates and the adjacent flanges of the sills. Said plates and said sills together practically constitute a box-beam; and the plates, 1, channel plates, 4:, angle plates, 2, and the gusset plates, 7, constitute, substantially, a box-column, the lower end of which is broadened by means of the gusset plates to make an extended attachment for the crossbeams, 8, and support the latter in a very strong manner. The cylinders, A, A, are supported by said crossbeams, each cyl- 5 inder being provided at opposite sides with brackets, 16, cast upon the exterior of the cylinder between its ends, the body of the cylinder below such bracket being of suitable diameter to extend between the ends Bolts, 17, extend through said brackets and the upper flange of the adjacent cross-beams and firmly bind the cylinders to said beams. Each cylinder has at its upper end two upright brackets, 18,

having upright faces bearing against the outer face of the adjacent draft sill, B; and each such bracket has a bolt hole, 19, which is elongated in an upright plane. A bolt, 20, extends through each such bolt hole and through the adjacent portion of the sill, B, and plate, 1. And each such bolt is to be drawn sufficiently tight to prevent the upper portion of the cylinder from leaning away from the adjacent sill when strain is applied by driving air or steam beneath the piston of said cylinder. But the elongation of the bolt holes, 19, allows downward movement of the adjacent brackets with reference to the bolts, 20. (See Figs. 1, 2,. and 2 This avoids shearing strain on said bolts, and avoiding the outward leaning of the cylinder reduces tendency of the cross-beams to bend downward at their outer ends. It will be understood that the maximum efficiency of the cross-beams can be attained only by continually applying the downward pressure of the cylinder to the cross-beam as closely as may be to the sills, and this is accomplished by holding the upper end of the cylinder in the manner described holding the upper ends of the cylinder against lateral movement while permitt-ing downward yielding. In each cylinder is a piston, 21, having an upright piston rod, 22, having its upper end hinged to a bracket, 3, which is secured immovably to the bottom of the car. A fluid supply pipe, 24, is tapped into the lower end of each cylinder and leads to any suitable source of steam, air, or other fluid supply (not shown,) whereby such fluid may be forced into such cylinder for raising the piston of said cylinder.

I claim as my invention,

In a dump car, the combination with two parallel draft sills. of a box column located between and extending below said sills, gusset plates applied to said column below said sills, cross-beams secured to said gusset plates, cylinders extending between said cross-beams and having brackets resting upon and secured to said cross} beams, and means for holding the upper of the cylinders against lateral movement while permitting downward yielding, substantially as described.

2. In a dump car, the combination with two parallel draft sills, of wall plates applied to the inner faces of said sills, upright channel plates applied transversely between said wall plates, gusset plates applied to the lower ends of said channel plates, cross-beams secured to said gusset plates and said channel plates, cylinders ex tending between said cross-beams and having brackets resting upon and secured to said cross-beams, and means for holding the upper ends of the cylinders against lateral movement while permitting downward yielding, substantially as described.
